How to do Jackknife Sit-Ups
Jackknife Sit Ups
Extend your legs and lift them at an angle of about 30-45 degrees from the floor while your arms should be kept parallel to your legs. If you find it difficult, you may do the exercise by flexing your knees.
Tips
- Contract your core muscles when you start this exercise to get the most benefits.
- Instead of engaging your hips, make sure that you use abdominal strength to lift your legs.
Variation with Medicine Ball
It replicates the movement of jackknife sit-ups but adds extra resistance, and is thus suitable for advanced gym trainees.
